Abstract

The utility model discloses a saw blade tension device, which comprises a bracing frame and a belt wheel holder which are mounted on a main body, wherein the belt wheel holder is mounted on the bracing frame through a bolt, one portion of the bolt, which is exposed outside the bracing frame, is provided with a regulating nut, and one portion of the regulating nut, which is exposed out of the main body, is provided with a knob. The saw blade tension device tightens saw blades through regulating the distance between two belt wheels, has simple structure, low cost, convenient operation, can reduce amount of labor of workers, and improves working efficiency.

Description

The saw blade tensioning apparatus
Technical field
The utility model relates to a kind of electric cutting tool of mechanical field, is specifically related to a kind of saw blade tensioning apparatus of band saw.
Background technology
Band saw is widely used in mechanical field, can be used to materials such as cutting panels of wood, plastic plate, compressive plate, glued board and fiberboard.The band saw lax processing that is unfavorable for workpiece of saw blade in use needs the tensioning saw blade.The saw blade tensioning device structure complexity of the band saw that exists in the market and use, complex operation influences the raising of operating efficiency.
The utility model content
Goal of the invention:, the utility model proposes a kind of simple in structure, easy to operate saw blade tensioning apparatus in order to overcome the deficiencies in the prior art.
Technical scheme: saw blade tensioning apparatus of the present utility model comprises bracing frame and the belt wheel holder that is installed on the body, the belt wheel holder is installed on the bracing frame by bolt, the part that bolt exposes bracing frame is provided with adjusting nut, and the part that adjusting nut exposes body is provided with knob.
Wherein, the belt wheel holder is provided with outstanding cylinder, and support frame as described above is provided with the vertical slots that can supply this outstanding cylinder to slide up and down; Belt wheel holder below is provided with the belt wheel installing plate, and bracing frame is provided with the bracing frame installing plate.
Saw blade tensioning apparatus of the present utility model is fixed on bracing frame on the body by the bracing frame installing plate in use, and the part that adjusting nut exposes body is provided with knob.Belt wheel is installed in by wheel shaft on the belt wheel installing plate of holder below, because saw blade is enclosed within on driving wheel and the driven pulley, so can reach the purpose of tensioning saw blade by the distance of regulating driven pulley and driving wheel two axles.When rotation during knob, the degree of depth that bolt screws in the adjusting nut increases, and drives the belt wheel mount pad and moves upward, and then drive and superincumbent belt wheel is installed is moved upward, and increases the distance between two belt wheels, the saw blade tensioning.When needs relax saw blade, the opposite spin knob, the degree of depth that bolt screws in the adjusting nut reduces, and the belt wheel mount pad moves downward, and drives belt wheel and moves downward, and the distance between the two belt wheel wheel shafts reduces, and saw blade is lax, is convenient to dismantle saw blade.
Beneficial effect: saw blade tensioning device structure of the present utility model is simple, with low cost, easy to operate, can reduce workman's amount of labour, increases work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is installed in schematic diagram on the body for the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
Shown in attached Fig. 1 and 2, saw blade tensioning apparatus of the present utility model comprises bracing frame 2 and the belt wheel holder 3 that is installed on the body 1, belt wheel holder 3 is installed on the bracing frame 2 by bolt 4, the part that bolt 4 exposes bracing frame 2 is provided with adjusting nut 5, the part that adjusting nut 5 exposes body 1 is provided with knob 6. wherein, belt wheel holder 3 is provided with outstanding cylinder 31, and bracing frame 2 is provided with the vertical slots 21 that can supply this outstanding cylinder 31 to slide up and down; Belt wheel holder 3 belows are provided with belt wheel installing plate 32, and bracing frame 2 is provided with bracing frame installing plate 22.
Saw blade tensioning apparatus of the present utility model is fixed on bracing frame 2 on the body 1 by bracing frame installing plate 22 in use, and the part that adjusting nut 5 exposes body is provided with knob 6.Belt wheel is installed in by wheel shaft on the belt wheel installing plate 32 of holder below, because saw blade is enclosed within on driving wheel and the driven pulley, so can reach the purpose of tensioning saw blade by the distance of regulating driven pulley and driving wheel two axles.When rotation during knob 6, the degree of depth that bolt 4 screws in the adjusting nuts 5 increase, and drive belt wheel mount pad 3 and move upward, and then drive and superincumbent belt wheel is installed is moved upward, and increase the distance between two belt wheels, the saw blade tensioning.When needs relax saw blade, opposite spin knob 6, the degree of depth that bolt 4 screws in the adjusting nut 5 reduces, and belt wheel mount pad 3 moves downward, and drives belt wheel and moves downward, and the distance between the two belt wheel wheel shafts reduces, and saw blade is lax, is convenient to dismantle saw blade.
The above only is a preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
